All of our pulleys are designed to allow usage of a second wheel bearing on V2 models of boosted boards. Our testing has shown less wheel and pulley wear along with greater stability while riding. You MUST remove the small silver spacer when installing with 2nd wheel bearing.
V3 Models, Stealth MiniS and MiniX do not use second wheel bearing.
